Identifying which early mathematics skills have the largest effects on later mathematics achievement has important implications. However, regression-based estimates often rely on untested assumptions: (a) Scores on different mathematics skills reflect unique constructs, and (b) other factors affecting early and later mathematics achievement are…

In this paper, the Classroom Learning Activities Checklist (CLAC) is proposed as a classroom observation measure that effectively captures the classroom environments and strategies that support self-regulation via task-oriented learning in young students. The CLAC's dimensionality, reliability, and concurrent and predictive validity evidence are…

This study aims to develop a short German version of the Self Description Questionnaire (SDQ I-GS) in order to present a robust economical instrument for measuring German preadolescents' multidimensional self-concept. A full German version of the SDQ I (SDQ I-G) that maintained the original structure and thus length of the English original SDQ I…

The purpose of the present study was to examine validity aspects of teachers' judgements of pupils' reading skills. Data come from Sweden's participation in the Progress in International Reading Literacy Study (PIRLS) 2001, for Grades 3 and 4. For pupils at the same achievement levels, as measured by PIRLS 2001 test, teachers' judgements of…

In this study we investigated relationships between convergent and divergent thinking with an emphasis on fluency, originality, flexibility and elaboration in the mathematical domain. A related purpose was to examine relationships between problem types in mathematical tasks. The math section of a performance-based assessment was used to assess 857…
